Step‑by‑Step Instructions for Spinach and Artichoke Chicken Casserole
Step 1: Preheat the Oven
Begin your culinary journey by preheating your oven to 350°F (175°C). This is the perfect temperature to ensure your Spinach and Artichoke Chicken Casserole bakes evenly, creating a golden, bubbly top that is irresistible. While the oven warms up, prepare the other ingredients for a smooth transition.
Step 2: Prepare the Chicken
In a large bowl, season your cubed boneless, skinless chicken breast generously with kosher salt. Allow it to rest at room temperature for at least 20 minutes. This optional dry brining step will enhance the chicken’s moisture and flavor, making each bite in your casserole even more delicious.
Step 3: Drain the Artichokes
Next, take a moment to drain your canned artichoke hearts thoroughly. Use a clean kitchen towel to absorb any excess liquid, ensuring you have the best texture in your casserole. Once drained, chop the artichokes into smaller pieces and set them aside, ready to mingle with the other ingredients.
Step 4: Squeeze Spinach
Grab your thawed frozen chopped spinach and squeeze out any excess moisture using clean hands or a cheesecloth. This crucial step prevents a watery casserole and ensures your Spinach and Artichoke Chicken Casserole holds its delightful shape. Set the drained spinach aside, moving on to the chicken.
Step 5: Cook the Chicken
In a large skillet, heat a drizzle of avocado or olive oil over medium heat. Once hot, add the seasoned chicken pieces, cooking for 4-6 minutes until they are mostly cooked through and lightly browned. Stir occasionally to prevent sticking, then remove the chicken from the skillet and set aside.
Step 6: Blend the Filling
In a food processor, combine the cottage cheese, garlic cloves, kosher salt, black pepper, and onion powder. Blend until smooth and creamy, creating a luscious mixture that will bind the Spinach and Artichoke Chicken Casserole together. Set the blended filling aside, excited for the next step.
Step 7: Combine Ingredients
In a large baking dish, mix the cooked chicken, squeezed spinach, chopped artichokes, and the creamy cottage cheese blend. Sprinkle in ⅔ of the shredded mozzarella and grated parmesan, stirring well to combine all the components thoroughly. This mixture is the heart of your delicious casserole, ready for the oven.
Step 8: Bake Covered
Cover the baking dish with aluminum foil, sealing it tightly to trap moisture. Bake in your preheated oven for 20 minutes. This allows the flavors to meld beautifully, ensuring your Spinach and Artichoke Chicken Casserole is moist and flavorful when you uncover it.
Step 9: Add Cheese Topping
After 20 minutes, carefully remove the foil and sprinkle the remaining mozzarella and parmesan cheese over the top of the casserole. Return it to the oven uncovered for an additional 10 minutes. Watch closely as the cheese melts and turns bubbly, promising a delightful finish.
Step 10: Broil for Perfection
To achieve a crispy, golden crust, switch your oven to broil for the last few minutes of cooking. Keep a watchful eye during this time, as it takes only a short while for the top to reach that perfect bubbling texture. Once done, your Spinach and Artichoke Chicken Casserole is ready to impress.
